Pi smackdown at Perimeter Institute

In this intense showdown, “standup mathematician” Matt Parker and Perimeter Institute’s Tibra Ali go head-to-head in a battle to concisely describe the ratio of a circle’s circumference to its diameter.

Given that pi was vital in the naming of Perimeter Institute (PI), we’re pleased to salute this beautiful irrational number and all of its endless decimal places.

Perimeter Institute is the world’s largest research hub devoted to theoretical physics. The independent Institute was founded in 1999 to foster breakthroughs in the fundamental understanding of our universe, from the smallest particles to the entire cosmos.
